Patent CA-1156794-A (CA)
Inventor: YEE KWOK C
IPC: C08J3/28

Granted: 1983-11-08
Abstract: Abstract Polymers of the type [=C(R)-C?C-(R)C=]n, formed by the solid-state polymerization of the corresponding diacetylene, have exten-sively delocalized   electron density along the chain, as required of a one-dimensional metal.  The polymer poly-ETCD, of this  form with R=alkylurethane, undergoes a reversible (green-red) thermo-chromic phase transition in the 117-137°C range.  Its Raman spectra reveal dramatic changes in the frequency and intensity of ?(C=C) and ?(C?C) bands as a function of source-frequency and of tempera-ture, as it is raised through the transition.  The changes result from the transition and from selective resonance enhancement of vibrations for domains with whose electronic transitions the source is in resonance.  The .pi.-electron delocalization is thus shown by Resonance Raman spectroscopy to occur over segments, or domains, along the polymer backbone.  The distribution of the domain-lengths is peaked at three values at 25°C but at one value above the tran-sition, for poly-ETCD samples prepared with high .gamma.-ray dosages. For 100 Mrad dosed samples, the domain-length distributlon is peaked around 6,  9, and 18 monomers-long at 25°C, and at about 9 monomers-long above the transition, as a result of polymer configurational changes which occur at the transition.

Abstract: ABSTRACT OF THE DISCLOSURE      A television tuner comprises a tuning circuit including a voltage controlled variable capacitance diode.  The tuning circuit is housed within a shield casing.  The shield casing is provided with a terminal for electrical connection to the variable capacitance diode and the terminal is supplied with a tuning voltage from a channel selecting apparatus.  A Zener diode is connected between the tuning voltage terminal and the shield casing, whereby the upper limit of the tuning voltage applied to the variable capacitance diode is restricted.  A predetermined voltage deter-minable dependent on the Zener diode is selected such that the tuning frequency established by the tuning circuit, when the predetermined voltage is applied to the variable capacitance diode, may be a predeter-mined upper limit frequency of a desired receiving frequency band.  The lower limit of the tuning voltage is also restricted so as not to become lower than a predetermined voltage.  Accordingly, the tuning frequency is prevented from being changed toward a higher or lower frequency deviating from the corres-ponding variation range of the desired receiving fre-quency band.

Granted: 1983-05-03
Abstract: ABSTRACT            The present invention relates to a map navigation system for aircraft (aeroplanes). The system comprises a map position indicator which on a map display shows a continuously updated course and position-oriented map image. The system also com-prises a computer unit (a calculating unit) which achieves the updating of the map image and also in an introductory stage, on the basis of the geographic co-ordinates of two or more points on the map, calculates the map scale on the map display. Transparencies of relevant navigation maps are used for the map position indicator. When preparing these pictures, no special consideration need be taken to the scale of the pictures, as this is calculated against the back-ground of the map image on the map display.

Granted: 1984-04-24
Abstract: Abstract A process for heating fluids to a relatively high temperature, such as sterilization of UHT temperature, in which the fluid, such as a liquid, is heated by direct contact with steam while it in the form of a very thin, free-falling film or a continuous falling stream so that heating of the fluid is accomplished without the fluid coming into contact with any surface and particularly metal surfaces which are hotter than the fluid product being heated and with minimum agitation and turbulence of the fluid product.  This procedure enables maximum and uniform heat penetration in a minimum time interval with the film or stream being maintained as thin as possible and unbroken by introducing steam at a relatively low velocity in a large volume vessel.  A flow control is incorporated into the apparatus to maintain a constant flow rate of fluid and to maintain a constant and critical fluid level in the bottom portion of the large volume vessel with the flow characteristics of the apparatus and the internal forces produced by the apparatus serving to counterbalance each other to provide a relatively simple hut yet accurate flow rate, and liquid level controls for the fluid being heated.

Abstract: ROTATING HEAT EXCHANGER FOR A DRYER     ABSTRACT OF THE DISCLOSURE         A compact and lightweight rotary heat exchanger for transferring heat from a hot gas flow to a cold gas flow has a low mass matrix in the form of a wheel.  The matrix is rotated at high speed into continuous consecutive contact with the respective hot and cold flows.  A fixed splitter runs along a diameter of the inner circumference of the matrix in order to segregate the flows as they pass radially across the matrix.  In combination with a domestic clothes dryer, the matrix is rotated directly on the drive shaft for the dryer's blower.  The matrix wheel rotates between heated dryer exhaust air and incoming room air to preheat the dryer intake air.

Abstract: ABSTRACT OF DISCLOSURE           A sonar survey apparatus comprises a submersible vessel having a structure adapted to receive a towing cable.  A sonar signal transmitter is mounted on the structure.  At least one acoustic reflector is mounted on the structure and is shaped to produce, in a focussing plane, line foci of acoustic echo signals received from remote positions. A line array of receiver transducers is mounted on the structure in the focussing plane and extends in a line substantially at right angles to the line foci.        Each receiver transducer element has an output for providing a signal representative of a focussed echo signal.  A processing apparatus accepts the output of each of the receiver transducer elements and has a control input and an output.  The processing apparatus is operable in response to a control signal produced by the movement of the vessel relative to a predetermined orientation, to select the output of a receiver transducer element, relating to a predetermined direction, for display.  Selection of a different receiver transducer element is thereby effected so that the processing apparatus continues to provide an output relating to the predetermined direction.

Abstract: ABSTRACT      For watering cattle with a high efficiency, an automatic drinking bowl is designed to give a high or low water inlet rate, which is automatically matched to the drinking rate of the cow or other animal so that drinking may take place as from a natural watering place.        When not in use, the spring-supported bowl is pushed downwards by the water in it shutting off an inlet valve. On a cow's drinking from the bowl, and so decreasing the weight of the water therein, the bowl is pushed upwards by the spring so that the water inlet valve is opened to an amount fully in step with the distance the bowl is moved upwards by the spring and so that the water inlet rate is very much in line with the animals drinking rate. The bowl is hinged to a support and joined with the inlet valve by a flexible hose. The water inlet opening is at the lowest point in the bowl and next to the water inlet opening, and there is a cleaning opening for clearing waste from the bowl.

Abstract: ABSTRACT OF THE DISCLOSURE    A separable integral donor connector with an improved clamping mechanism for use with flexible blood collection tubing is disclosed.  The device is positioned in line with the blood tubing between a phlebotomy needle and the col-lection bag.  Separation of the device is accomplished by manipulation and breaking of a thin frangible ring area and drawing the sections of the device apart.  This separation exposes an internally-mounted needle that may be used for penetration of sample collection tube ciosures and subsequent collection of blood samples,  The present embodiment of this invention includes improved manually-operated clamping means that are flexibly biased away from the blood tubing.  Clamp-ing jaws of differing lengths are disclosed which, when engaged. overlap and cause an area of tubing to be collapsed into a distinctive, S-shaped configuration which crimps and more effectively seals the tubing against blood flow.  The clamping device is free from restraints permitting sample, one-handed operation, as well as the broadest control over the blood flow.
